9240f51352 Fixed a major oversight in the interrupt handling: when a user space
application got interrupted, thread_at_kernel_exit() was called - but
that expected interrupts to be enabled for signal handling.
However, only exceptions 3 (breakpoint) and 99 (syscall) are trap
gates, and thus, only those actually had interrupt enabled at that
point.
If a KILL signal was pending when a hardware interrupt interrupted a
user space thread you were entering KDL before ("acquire_sem() called
with interrupts turned off").
Thanks to mouse interrupts I finally got this often enough to find
this...

2b028fcaa0 Removed one TODO from the list: in case pages_io() fails, read_chunk_into_cache()
will no longer panic, but free its allocated pages.
I ran into this because BFS managed to create a file without data stream but
with a length larger than 0...

aeef8a1098 Reverted to the previous version. I was too quick; the boot loader
doesn't link against libsupc++ and still needs the symbol.

758b1d0e05 Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
  declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
  explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
  something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
  'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
  is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
  Otherwise the an inner class with that name is considered as friend.
  gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

04cd47db59 common_access() now follows the same logic as traversing paths: if the file system
doesn't export the fs_access() function, it assumes access is granted.

c5eb28a359 Now uses the new image_debug_lookup_user_symbol_address() call.
The stack frame that got interrupted were missing from the stack output
(and thus the call that got us into the kernel).

in user images - right now, it only finds the image name and base address.

571bb2b2a6 Simplified the x86 syscall interface a bit. We no longer pass a pointer
to the parameters nor the number of parameters; the kernel is able to
get both without problems.

The syscall functions in libroot (_kern_*()) are now self-contained
(they don't "jmp" to separate code anymore), which at least
theoretically allows gdb to print a stack trace with the syscall
function on the top when a thread is currently performing a syscall.
Practically it doesn't work yet, though, since those functions are
frameless (i.e. create no stack frame) which needs special support
I haven't implemented yet.

8fcd6b8e61 * renamed smp_boot.c to smp.cpp
* there is now a "Disable Hyper-Threading" safemode in the boot loader
* the SMP & HT menu items are now added in smp.cpp - and are only added
  if the system supports one of them.
* more cleanup to smp_apic.h
* removed cpuid() from the boot loader's support.S - instead, it will now
  use the one from the kernel.
* added a very weak HT detection: if the MP config only listed one CPU,
  and this CPU supports HT, we enable the other logic processor manually -
  as this currently doesn't work, it's disabled, though.

7121425eb5 Turns out we could remove a mount point...
Under BeOS remove_vnode() is failing in this case, which looks like a good idea to imitate.
Also, pipefs/rootfs didn't handle that case - they even removed the entry before calling
remove_vnode() - they now behave correctly. And also BFS now returns the actual error code
received from remove_vnode() instead of B_ERROR.

3ea780cdf9 If booted from an image, the list of possible boot partitions is now ordered by
some heuristic: when you booted from a CD, CDs are preferred; else, volumes with
names like "Haiku" or "System" are preferred - if someone has better ideas, please
shout.
Note, this heuristic will only come into play if the boot loader was loaded from
an image (ie. floppy/CD/network), and you didn't choose any boot device.
Added evil methods to the Stack class that come in handy (you can now directly
access the array) for this.

2db3fced5f Moved vfs_bootstrap_file_systems() and vfs_mount_boot_file_system() out of vfs.cpp
and into its own file vfs_boot.cpp.

Added basic support for booting from CD - it doesn't give CDs a higher priority,
so you could end up booting from HD when you didn't explicetly select "CD-ROM"
in the boot loader. Eventually, it should only boot from HD in this case, if
booting from CD failed (because of a missing boot partition or whatever).

fs_mount(), _kern_mount(), and _user_mount() will now return the dev_t of the
mounted device, and not just B_OK. Maybe we should have fs_unmount() work on
a dev_t instead of a path as well...

681779f1c8 Our close-on-exec flag handling was broken: it's supposed to be specified per slot, not
per file descriptor (a descriptor can be shared among several slots). There is now a
second table in the io_context structure that contains that information in a bitmap.
There are now two new (private) functions to control the close-on-exec flag, fd_close_on_exec(),
and fd_set_close_on_exec().
F_DUPFD, dup(), and dup2() are supposed to clear the close-on-exec flag on the duplicated
slot - this fixes bug  (no output after a redirect of a shell builtin).

08da6fccdd Introduced a sane concept of ownership for the team_args structure: now load_image_etc()
and exec_team() have an additional "kernel" argument and will copy the arguments
themselves (or rather, delegate that to create_team_arg()).
When team_create_thread_start() is called, it will take over ownership and is
responsible for deleting it - this also fixed a memory leak in case the user
stack area couldn't be created.
Also changed comment after exit_thread(): since this call only delivers a signal, the
code after it will still get executed.
This fixes the crashing symptom of bug .

67a7102658 Fixed a pretty fatal bug in the page fault handling: interrupts were enabled
even if "kernel_startup" was "true". Page faults are now no longer allowed
during kernel startup (and could be easily avoided). The only situation where
we accept page faults with interrupts turned off now is during a kernel debugger
session.
Added a command debug_debugger_running() to test for that situation.
kernel_debugger() no longer sets kernel_startup while it's running; there should
be no situation when this could be helpful.
Interrupts are no longer enabled when a page fault happens in the kernel
debugger.
This potentially fixes all sorts of problems, and not only in the kernel debugger,
it could also have affected SMP (will test later).

099ceb8f9d map_physical_memory() and its backend vm_map_physical_memory() did not map in the
pages, ie. they considered the areas to be B_LAZY_LOCK. But that doesn't really make
sense and potentially cause page faults where you wouldn't expect them (and where
it's not a good idea to trigger them).
Reworked display_mem() (used by the dw/db/ds commands in the kernel debugger) to
be a bit more sane, improved formatting, and allows it to work on non-existing
memory without a panic.
The "area" debugger command now also accepts an address (contained by the area)
as argument - and it will now always print out an error message if no matching
area could be found.
Replaced all dprintf() calls to kprintf() calls for the kernel debugger functions.

5b14757a30 We now have a consistent scheme what the file system should do with its root
node: like in BeOS, it *must* own the root node (ie. via publish_vnode()),
unlike in BeOS, it must also drop that reference on unmount (symmetrical
behaviour definitely makes more sense to me than the Be way).
Since all existing file systems for Haiku behaved differently, I brought them
in line (only pipefs already adhered to that new standard for some reason,
rootfs did only released the node, devfs did nothing - despite it's probably
not really useful to be able to unmount them).
fs_mount() will now panic if a file system does not do this correctly (useful
for file system developing).
Unmounting is now theoretically working again: when trying to unmount a BFS
volume, the kernel crashes in the block cache destruction... (but that's work
for tomorrow).

99e1c71ee6 - fixed a locking bug in the file cache: get_file_map() could been called with either
only a read lock on the inode, or without a lock at all (in case of prefetching) - it
  is now using the cache_ref's lock to make sure it's retrieved only once and doesn't
  waste/corrupts any memory.
- since that fix made it mandatory to fix write_chunk_into_cache() to not call pages_io()
  while holding the cache_ref's lock (was a to-do item before), I changed it to make
  that possible.
- It now also supports write-through caches in theory - as there is no way yet to tell
  a cache to work this way.
- Optimized for the not so uncommon case of writing the last part of a file that is not
  a multiple of the page size - it won't call pages_io() anymore then, but zero the rest
  of the page directly.
- vm_page_write_modified() is now calling write_page() without holding the cache_ref's
  lock as well.
The updated write_chunk_to_cache() is not so well tested, though, but appears to work
so far.

eab435cd59 vfs_get_vnode_cache() now only allocates a new cache if requested: this
prevents the system to allocate caches for files that don't use or have
a file cache (ie. only those can be mmap()ed!).
Therefore, cache_prefetch() no longer crashes when trying to prefetch
files without a file cache.
read_into_cache() no longer does anything if the requested size is 0.
Fixed a bug in cache_prefetch_vnode(): if the cache couldn't be retrieved,
it put the vnode, but didn't own it (the caller does).

d08379a80b * Now we deal with all x86 exceptions, i.e. we no longer panic() when a
user application performs a division by zero or causes a general
  protection fault. For some exceptions (e.g. machine check) I wasn't
  quite sure whether they can be caused by user apps at all, so we panic()
  in those cases. Wouldn't harm, if someone more knowledgable would check
  this, though.
* Removed the unused fault handling stuff, respectively moved the little
  that was used into x86/arch_int.c.

230a037ed4 Fixed a bad bug in vm_copy_on_write_area(): the area's cache offset was not taken
into account when remapping the pages read-only; it could have overwritten valid
page mappings this way. This was also the reason for the Terminal to crash - it
does now work as it should, although some keys don't work (like tab completion)).
vm_copy_area() no longer always sets B_KERNEL_WRITE_AREA if no kernel protection
was specified, but mirrors the userland protection (for example, the x86 MMU is
not able to have a page writable in kernel but not in userland). This caused
some areas to be read/write when read-only would have been enough.
vm_copy_area() now panics when vm_copy_on_write_area() fails - that's of course
no real solution, but it's bettern than letting it silently fail.
